英文摘要：

Development of information technology has greatly changed people＇s shopping style. Re-cently,a new e-business model of online group-buying gradually attracts the focus of the public. Under the theoretical background of both technology acceptance model and perceived risk, this study develops a re-search model exploring the impacting factors of online group-buying intention. We use survey method to col-lect data and use PLS （Partial Least Squares） Structural Equation Modeling （SEM） to test the research mod- el. We find that perceived enjoyment is the key factor of consumers＇ attitude toward online group-buying which further affects online group-buying intention. In addition, we find that perceived risk has no significant influence on online group-buying intention. This study can help advancing our understanding on the formation of online group-buying intention, and provide reference and suggestions for the marketing practice of online group-buying.
